INTRODUCTION
Main focus of agile is customer collaboration and satisfying
customer's real needs even in the early delivery of the software
system
It aims to improve the performance, quality and productivity of
the software development process
It is more than just another software development process or a
set of practices
In fact, agile is a mindset for software development, which
emphasizes on better ways of developing working software.

Summary
Agile Alliance
In Feburary 2001, 17 noted software developers, writers and
consultants(Kent Beck, Mike Beedle, Arie van Bennekum,
Alistair Cockburn, Ward Cunningham, Martin Fowler, James
Grenning, Jim Highsmith, Andrew Hunt, Ron Jeries, Jon
Kern, Brian Marick, Robert C. Martin, Stephen J. Mellor, Ken
Schwaber, Je Sutherland and Dave Thomas) came together
at the Snowbird ski resort, Utah to discuss methods of
developing software in a lighter, faster and human-centric

With these agreements, they coined the term Agile and
created the Agile Alliance, which is a non-prot organization
intended to promote agile development.
They agreed on four things namely respond to change, 4 core

Summary
MANIFESTO
These 17 professionals wrote a document called the Manifesto
for Agile Software Development, which focus on identifying the
values that yield the most attention to a development process.
We are uncovering better ways of developing software by doing
it and helping others do it.
Through this work we have come to value:
Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
That is, while there is value in the items on the right, we value
the items on the left more.

Our highest priority is to satisfy the customer through early
and continuous delivery of valuable software.
Welcome changing requirements, even late in development.
Agile processes harness change for the customer's competitive
advantage.
Deliver working software frequently, from a couple of weeks to
a couple of months, with a preference to the shorter timescale.
Business people and developers must work together daily
throughout the project.

The most ecient and eective method of conveying
information to and within a development team is face-to-face
conversation.
Working software is the primary measure of progress.
Agile processes promote sustainable development. The

Agile Methodologies
As of VersionOne's 2008 survey, named State of Agile
Development , 77% of the respondents told they practice XP,
Scrum, XP/ Scrum hybrid.
Some of the most common methodologies in Industry are :
Extreme Programming (XP) : primary focus on technical
practices
Scrum : focus primarily on project management agile practices
Lean Software Development (LSD)
Crystal, developed by Alistair Cockburn in 2001
Feature Driven Development (FDD)
All of the above, follow the approach of incremental
development as well as rapid delivery to the customer.

Success of software development is based on the abiltity to
embrace change in its development process
Primary focus of agile is customer collaboration and satisfying
customer's real needs even in the early delivery of the software
Agile oers solid business value for customers
It emphasies on four key issues: the signicance of
self-organizing teams, communication and collaboration, faster
delivery to satisfy the customer, and an identication that
change symbolizes an opportunity
